zebrafish vs mice models

2014;5:3475. Humans and mice share many common genetic features and by examining the physiology, anatomy and metabolism of a mouse, scientists can gain a valuable insight into how humans function. However, the use of an inappropriate animal model that is not similar to human pathology or disease progression can slow the development of new therapeutics. The situation is completely different for the ClC-2 protein. GlialCAM/MLC1 modulates LRRC8/VRAC currents in an indirect manner: implications for megalencephalic leukoencephalopathy. However, in vitro studies suggest the possibility that it may act as a negative regulator of MLC1 and ClC-2 [29, 32]. Most movement disorders lack effective p… To test this hypothesis, we constructed an adenovirus expressing zebrafish mlc1 and infected Glialcam−/− mouse primary astrocytes. The zebrafish genome has been fully sequenced, which is a must-have for model organisms nowadays. zfmlc1 and hMLC1 overexpressed in primary Glialcam−/− astrocytes are located at cell-cell junctions. All experimental procedures were performed in accordance with the European Community Guidelines on Animal Care and Experimentation and were approved by the institutional animal care and use committees. Unexpectedly, mlc1 protein levels were unchanged in glialcama−/− zebrafish (Fig. 4e-f). Orphanet J Rare Dis 14, 268 (2019). Supernatants were quantified using BCA kit (Pierce) and mixed with SDS loading sample buffer. They compared innate immune responses to the toll-like receptor (TLR)-3 agonist polyinosinic:polycytidylic acid (poly[I:C]) and TLR-7/8 agonist resiquimod (R848). 2018;119:88–99. Pannasch U, Vargova L, Reingruber J, Ezan P, Holcman D, Giaume C, et al. The timing of the adoption of zebrafish as an emerging model organism could not be better, as mouse studies often fail to translate to humans. 6d). 2018;98:1493–590. They are also very cheap; however, they do require more space than other model organisms such as flies. CAS  Previous immunofluorescence experiments detected similar localization of glialcama and mlc1 in radial glial cell bodies and their processes in the brain (Fig. Disrupting MLC1 and GlialCAM and ClC-2 interactions in leukodystrophy entails glial chloride channel dysfunction. Cancer Stem Cells and Tumor-initiating cells. This finding suggests zebrafish but not mice are an appropriate model to study innate mucosal immune responses to poly[I:C], as they have similar response kinetics as humans. Since the majority of cases of CdLS are caused by haploinsufficiency for NIPBL (Nipped‐B‐like, which encodes a cohesin‐associated protein), we have developed mouse and zebrafish models of CdLS by using molecular genetic tools to create Nipbl‐deficient mice and zebrafish (Nipbl +/− mice, zebrafish nipbl morphants). © 2021 BioMed Central Ltd unless otherwise stated. 2015;77:114–31. No major differences were found in the vacuolization phenotype between both mice models [ 15 ]. A holodeck for lab animals. Indicating that both zebrafish and mice, are appropriate models to study immune mechanisms of R848 challenge. 4a). Neurobiol Dis. 3). Pflugers Arch - Eur J Physiol. Hoegg-Beiler MB, Sirisi S, Orozco IJ, Ferrer I, Hohensee S, Auberson M, et al. We do not know which could be the role of glialcamb in zebrafish. Estévez R, Elorza-Vidal X, Gaitán-Peñas H, Pérez-Rius C, Armand-Ugón M, Alonso-Gardón M, et al. While mouse “knockouts” are generated by isolating embryoni… Localization of GlialCAM (a) and Mlc1 (b) in primary astrocytes from wild-type (WT, left), Glialcam−/− (middle) and Glialcam−/− complemented with adenoviruses expressing human GlialCAM (right). Ann Neurol. Xie H, Wang J, Dhaunchak AS, Shang J, Kou L, Guo M, et al. Zebrafish have a single Lxrα ortholog, making this model organism potentially useful for examining Srebp regulation by Lxr in the future (Bertrand et al., 2007; Archer et al., 2008). Therefore, we analysed the brain phenotype of glialcama−/− zebrafish by MRI. We also show that additional disruption of mlc1 in glialcama knockout zebrafish or in Glialcam knockout mice does not potentiate the vacuolating phenotype characteristic of MLC disease, indicating that loss-of-function mutations in these genes cause leukodystrophy through a common pathway. Jeworutzki E, Lagostena L, Elorza-Vidal X, López-Hernández T, Estévez R, Pusch M. GlialCAM, a CLC-2 cl(−) channel subunit, activates the slow gate of CLC chloride channels. Click photos for enlargement. In addition, measurements of brain volume revealed that the whole brain is bigger in MLC knockout models than in its wild-type littermates [14, 16, 29]. Dubey M, Brouwers E, Hamilton EMC, Stiedl O, Bugiani M, Koch H, et al. Hum Mol Genet. The deletion changes the open reading frame after the seventh amino acid and causes a premature stop codon at amino acid 28 (Fig. 2012;73:951–61. * p < 0.05 vs wild-type astrocytes. Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License. For example, zebrafish show some overt differences in physiology from mammals, such as the external fertilization that does not mimic uterine development in the latter (d'Amora and Giordani, 2018).Another problem is that zebrafish present rather limited range of behavioral phenomena (e.g., it … Am J Hum Genet. Zebrafish are widely used in research due to their numerous beneficial properties. 2011;108:8467–72. Interestingly, zebrafish mlc1 was located at astrocyte junctions, suggesting that it may not need Glialcama for targeting to astrocyte junctions (Fig. Scale bar: 10 μm. Furthermore, glialcama−/− and mlc1−/− zebrafish were pair-wise mated to obtain animals knockout for both genes or knockout for a single gene and heterozygous for the other. Molecular mechanisms of MLC1 and GLIALCAM mutations in megalencephalic leukoencephalopathy with subcortical cysts. As zebrafish are kept at 28 °C, which is a lower temperature than the temperature mice are kept (37 °C), we reasoned that stabilization of MLC1 by GlialCAM might not be necessary at lower temperatures. In order to compare the size of the telencephalon relative to the whole brain of the different groups one-way analysis of variance (ANOVA) was performed and indicated that the size was larger in all mutants as compared to wild type (*p < 0.05; **p < 0.005) (n = 3). JACI, © 2014 - 2021 Immunopaedia.org - As with the Glialcam−/− mouse or the mlc1−/− zebrafish [15, 29], the homozygous glialcama−/− zebrafish turned out to be viable and fertile, with the expected mendelian ratio among adult descendants. Int J Mol Sci. Localization and functional analyses of the MLC1 protein involved in megalencephalic leukoencephalopathy with subcortical cysts. We used antibodies detecting the zebrafish MLC1 or the HA epitope, which did not detect the endogenous Mlc1. The aim of this study is to preliminary evaluate the antiparkinsonian activity of furanocoumarin—xanthotoxin, in two behavioral animal models, zebrafish larvae treated with 6-hydroxydopamine and mice treated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine in order to compare both models. The zebrafish facility at the Department of Molecular Biology and Genetics, Aarhus University, Denmark. In mouse primary astrocytes, lack of GlialCAM (Fig. 1d and f, respectively). 2014;35:1175–8. The size of telencephalon was bigger in mutant zebrafish as compared to wild type (white arrows). Zebrafish seem to have only a single srebf1 transcript variant, unlike higher vertebrates, in whom two major variants encoding Srebp1a and Srebp1c are present. a An allele with a deletion of 7 nucleotides in glialcama (Δ7, from now on −/−) was generated using a TALEN nuclease. Megalencephalic leukoencephalopathy with subcortical cysts protein 1 regulates glial surface localization of GLIALCAM from fish to humans. However, as other in vivo models, zebrafish present certain limitations in regard to modeling NDDs. Due to their small size and the relatively simple nature of … Densitometric analysis (n = 3) indicates that Mlc1 levels were reduced in astrocytes from Glialcam−/− mice and expression was recovered after expression of GlialCAM using adenoviruses. This work was supported in part by the Spanish Ministerio de Ciencia e Innovación (MICINN) (SAF2015–70377 and RTI2018–093493-B-I00 to RE); the Generalitat de Catalunya (SGR2014–1178 to RE, SGR014–2016 to VN), the Instituto de Salud Carlos III by an intramural project from CIBERER to RE and PI16/00267-R-Feder to VN. Generation of a glialcama knockout line in zebrafish. CP-R, MF, AA, MNE, MLD and AB performed zebrafish studies. Histopathology of brain sections from Mlc1−/− and Glialcam−/− mice revealed the presence of vacuolization mainly in fibre tracts of the cerebellum [15, 16, 21, 33]. Regulation of Immunity & the Microbiome, 10. We previously described that the teleost-specific genome duplication yielded two glialcam paralogues: glialcama and glialcamb [29]. 6a) and protein levels (Fig. Model organisms are drawn from all three domains of life, as well as viruses.The most widely studied prokaryotic model organism is Escherichia coli (E. coli), which has been intensively investigated for over 60 years.It is a common, gram-negative gut bacterium which can be grown and cultured easily and inexpensively in a laboratory setting.

In order to obtain astrocyte cultures arrested in the cell cycle, medium was replaced and cytosine β-D-arabinofuranoside (AraC, Sigma) (2 μM) was added. Two other independent experiments gave similar results. Zebrafish are remarkably biologically similar to people and share the majority of the same genes as humans, making them an important model for understanding how genes work in … The size of telencephalon was bigger in mutant zebrafish as compared to wild type (white arrows). Identification and characterization of the zebrafish ClC-2 chloride channel orthologs. a Quantitative real-time PCR to determine levels of glialcama, glialcamb and mlc1 messenger RNA in the brain of glialcama−/− zebrafish. In mice, ablation of GlialCAM strongly reduced the labelling for Mlc1 and changed its localization in Bergmann glia and at astrocytic end-feet along blood vessels [15, 16]. Second, the vacuolating phenotype of Clcn2−/− mice increased after additional disruption of Glialcam [15]. c, d Overexpression using adenoviruses of mlc1 from zebrafish (zfmlc1, c) and human HA-tagged MLC1 (hMLC1, d) detected both MLC1 proteins at cell-cell junctions (arrowheads) in primary astrocytes isolated form Glialcam−/− mice. c glialcama expression in the optic tract (Ot) (arrowheads) and diffusely in cell bodies of the preoptic region (asterisk) of wild type fish (dotted line: optic tract/preoptic region boundary).
